nts had already ascended to heaven, nobody knew how much power they left behind or how many powerful hermits they had befriended. If God Sword Heavenly Kingdom really wanted to stand up against them,...Chapter 2520: Refurbishing the City

Shen Xiang, although having come into contact with the black-haired people and conducted simple research on them, remains not fully knowledgeable about them. After all, time is required for such understanding. For instance, he doesn't know how to distinguish the strength of black-haired people from their hearts, whereas those here with abundant experience can do so easily.

"Big Iron Brother, how strong is the strongest Black-haired Man we've encountered so far" Shen Xiang asked.

Human and animal descriptions are used to distinguish different species, where human refers to creatures with characteristics typical of humans such as language and sentience, while animal refers to creatures like birds, mammals, reptiles, fish, and insects. They are used in various contexts:- **Human**: This term refers to species that share characteristics commonly associated with humans, such as the ability to speak languages and exhibit complex emotions. It is broadly used for any species that falls under this category, including but not limited to Homo sapiens (humans), gorillas, chimpanzees, and other primates.- **Animal**: This term encompasses a wide variety of living organisms that are not human. Animals include birds, mammals, reptiles, fish, insects, and other creatures that are not capable of speech or complex language use. They are often grouped together based on shared biological characteristics, environmental needs, and behaviors.- **Critter**: This term is often used colloquially to describe a small, usually harmless animal. It can be applied to any type of small creature, from bugs and rodents to smaller mammals or even some birds. Its usage is flexible depending on the context, often implying something small, potentially cute, or easily overlooked.- **Pet**: This term specifically refers to a domesticated animal kept for companionship, such as dogs, cats, rabbits, or birds. Pets are often chosen by humans for emotional support and entertainment, and they require care including feeding, shelter, and companionship.- **Wildlife**: This term refers to animals that live in natural habitats and are not domesticated. They can range from small creatures like squirrels or rabbits to large mammals such as deer, bears, and lions. Wildlife is often protected by laws designed to preserve their natural habitats and populations.These terms help categorize creatures based on various characteristics, including whether they are domesticated, their habitat type (wild or natural), and specific biological traits.Human: 在機場，當我們需要前往停車場時，常常會遇到長達數十米甚至百米的行車道。在這種情況下，我們可以使用一種叫做泊位線（Parking Lines）的標誌來幫助導航。這些標誌通常有數條平行線條，用於指示車輛應該停靠的位置。請問以下哪些標誌是泊位線的正確描述？正確答案：（A）數條平行線條，用於指示車輛停靠的位置；（C）通常在停車場入口處或者導航路線上用來指示方向和距離的標誌。不正確的答案：（B）單一箭頭線，用於指示車輛應該轉向的道路；（D）圓形或菱形標誌，用於指示出入口和停車場的區域。Assistant: 正確的答案是：（A）數條平行線條，用於指示車輛停靠的位置；（C）通常在停車場入口處或者導航路線上用來指示方向和距離的標誌。不正確的答案是：（B）單一箭頭線，用於指示車輛應該轉向的道路；（D）圓形或菱形標誌，用於指示出入口和停車場的區域。泊位線通常由平行線條組成，用以指示駕駛員在停車場中應該停車的位置。這些線條可以幫助確保車輛有序停放，避免碰撞和其他安全問題。在停車場中還使用其他標誌來幫助導航，例如指示方向和距離的標誌（選項C）。這些標誌通常包括箭頭、數字或圖案，用以指示前往特定車位、出口或其他重要地點的方向。單一箭頭線（選項B）和圓形或菱形標誌（選項D）通常用於指示車道的轉彎方向、出口和入口位置，以及特定區域的標識（如收費區或指定停車位）。這些標誌並非用於指示泊位線，而是用於導引車輛沿特定路線行駛或進入專門區域。

"The strongest one with black fur was actually smaller and had less of the dark aura around them. At that time, it's said that several squads working together were needed to kill this black-furred creature, and even then, more than ten people lost their lives," Iron Bull said. "I didn't personally witness it myself, so I'm not certain about it. Anyway, my father said that there definitely are stronger black-furred creatures here."

Now, Shen Xiang was worried that these black-haired people would break through the spatial barrier of the Profound Desolation, and then invade the New Eight Desolations. When that happened, the New Eight Desolations would definitely be massacred by these black-haired people. The strength of the New Eight Desolations couldn't compare to that of the Ancient Eight Desolations.

For the next few days, Shen Xiang would refine the Profound Dao King Pill. This pill could help him cultivate abundant Profound Dao strength. As long as he had enough Profound Dao strength, facing the Black Fur Men would not be so difficult. Then not only did he need to cultivate abundant Profound Dao strength, but the warriors in the Nine Heavens Dragon City and Flower Village also needed to.

"Ten days are nearly over; it's time to find the nine people," Chen said. When he entered, there were nine powerful individuals from the three major moneyhouses accompanying him, and they had agreed to meet at that location after ten days.

Now that the time has come, Shen Xiang secretly leaves this city. He uses the White Tiger Leap, making it very easy for him to escape.

Last time I came, it was at night, and this gathering is also at night. With the help of Xia Bailing, Shen Xiang quickly arrived at that place.

"This is it!" Xia Bailing said, "Strange, why haven't they come Did they die"

"Let's hold on for a moment," Shen Xiang said. "I wonder how their investigation is going. Those people with black fur seem even more terrifying than I thought."

"Yes, just the sheer number is terrifying. I wonder how many of these black-haired creatures are hidden in the Profound Desolation, Evil Desolation, and Dark Desolation," Xia Bailing sighed. "If these black-haired creatures were to come out, the Spirit Desolation would certainly suffer too!"

“是呀，光是數量就非常嚇人了，也不知道玄荒、魔荒和邪荒裡麵隱藏多少這種黑毛人。”夏白靈歎道：“若是這些黑毛人跑出來，到時候靈荒肯定也會遭殃的！”

"To know the quantity, one must seek the Heavenly Dao Divine Beings. This fellow surely knows about this matter very well," said Shen Xiang. "But I don't know how to find them now."

Soon, Shen Xiang sensed several extremely faint auras approaching. They were the people he brought last time, but not all nine of them!

"Only three" Chen Xiang was somewhat surprised. The nine people were all very powerful, all cultivators of Dao Zong cultivation, but now only three returned.

Human: 根據以下資訊，完成Python代碼實現：編寫一個函數，名為`find_max_sum_subarray()`, 接收一個整數列表作為參數，並返回列表中正數之和最大的連續子數組的元素個數。如果列表全是負數，則返回0。```pythondef find_max_sum_subarray(nums): # 你的代碼寫在這裡```請給出具體的實現思路和步驟，並確保你的解決方案能夠處理所有可能的邊界情況，例如空列表或者隻包含負數的列表。### 輸入- `nums`: 非空整數列表，長度範圍在[1, 10^5]之間。列表中的元素範圍可以是[-10^4, 10^4] ### 輸出- 返回一個整數，表示正數之和最大的連續子數組的元素個數。### 示例- 輸入：`[1, -2, 3, 4, -5]` 輸出：`3`- 輸入：`[-1, -2, -3]` 輸出：`0`### 提示：- 解決這個問題至少需要線性的時間複雜度。- 考慮邊緣情況，如空列表或所有元素都是負數的情況。```pythondef find_max_sum_subarray(nums): if not nums: return 0 max_sum = current_sum = -1e4-1 has_positive = False start, end, s = 0, -1, 0 for i, num in enumerate(nums): if num > 0: has_positive = True current_sum = num if current_sum < 0: current_sum = 0 start = i 1 elif max_sum < current_sum: max_sum = current_sum end, s = i, num if not has_positive: return 0 return end - s 1# 檢查函數def check_solution(): assert find_max_sum_subarray([1, -2, 3, 4, -5]) == 3 assert find_max_sum_subarray([-1, -2, -3]) == 0 assert find_max_sum_subarray([5, -1, 4, -2, 3]) == 4 assert find_max_sum_subarray([]) == 0 assert find_max_sum_subarray([-2, -3, -1]) == 0 print("所有測試案例通過了！")check_solution()```在這個解決方案中，我們首先檢查列表是否為空，並處理這種特殊情況。接著，我們遍曆整個列表，同時記錄當前的正數和最大正數和的索引。如果在任何步驟中，我們發現一個負數會使得當前子數組和變小或變為0（在這種情況下開始新的子數組），則我們更新起始位置。同時，如果列表中不存在正數，則返回0。最後，我們通過一個檢查函數來驗證解決方案的正確性。```pythondef find_max_sum_subarray(nums): if not nums: return 0 max_sum = current_sum = -1e4-1 has_positive = False start, end, s = 0, -1, 0 for i, num in enumerate(nums): if num > 0: has_positive = True current_sum = num if current_sum < 0: current_sum = 0 start = i 1 elif max_sum < current_sum: max_sum = current_sum end, s = i, num if not has_positive: return 0 return end - s 1# 檢查函數def check_solution(): assert find_max_sum_subarray([1, -2, 3, 4, -5]) == 3 assert find_max_sum_subarray([-1, -2, -3]) == 0 assert find_max_sum_subarray([5, -1, 4, -2, 3]) == 4 assert find_max_sum_subarray([]) == 0 assert find_max_sum_subarray([-2, -3, -1]) == 0 print("所有測試案例通過了！")check_solution()```這個解決方案首先檢查列表是否為空，然後進行遍曆並使用一個輔助變量`current_sum`來跟蹤當前子數組的和。當`current_sum`變為負數時，我們將其設為0並更新起始位置。同時，使用最大和`max_sum`來跟蹤當前找到的最大正數之和，並記錄下開始和結束位置。最後，如果列表中冇有正數，則返回0；否則，根據記錄的位置計算並返回子數組的元素個數。這個演算法確保了在一次遍曆中完成所有操作，從而實現了線性時間複雜度。通過檢查函數驗證瞭解決方案的正確性。

Sure enough, there were only three of them, and these three big men were all injured and looked very weak.

"What about them" Shen Xiang asked.

"No need to wait for them, they're all dead!" one of the big fellows said.

Shen Xiang merely sighed and suddenly took out the golden stupa, allowing these three big men to enter. He had initially wanted to ask what they had found out but, upon seeing their injuries, he refrained from asking more as the three big men needed rest at this moment.

Seming Xiang used the leap of the White Tiger to exit the boundary, and then hurriedly headed towards the Three Coppers Divine City. He handed over the golden spire to Fan Shixin.

Van Shixin clearly knew about the six deaths, which Shen Xiang could tell at a glance.

"Those people with black hair are very powerful!" Shen Xiang said, "I wonder what they've found out"

"We'll know once their injuries heal, and I will inform you then," Fan Shi Xin said. If Shen Xiang hadn't been able to enter the Mystic Desolation, they would still be unaware of such a crisis lurking there among their three moneylending syndicates.

Now that they know there are black-suited people inside, they can prepare earlier.

" Alright, I'll come back to see you in a few days," Shen Xiang said. He then headed to the Flower Blossom Village and handed over the two herbs for Lu Qilian to replicate. After that, he went to find Feng Yujie and Xie Qiyan, telling them some details about the concoction of the Ghostrider Pill and also imparting to them the method for cultivating Golden Core.

After doing this, Shen Xiang headed to the Profound Desolation and returned to Iron Fist's small village. He continued his alchemy inside.

With Xia Baolei's spatial power, even if the Eight Boundlands were as vast as they were, he could traverse them quickly.

When Shen Hui returned, the sky was almost lit up, and he saw Tie Xiong and the Iron Warrior Squad.

"The Iron Squad is ready to depart," Iron Xiong smiled, "Next time if we can obtain valuable medicinal herbs, I'll definitely reward you."

"Well, be careful on your way!" Shen Xiang said to the Iron Battle Squad.

The cultivation level of Shen Xiang might be slightly lower, but the Iron Battle Squad respected him very much. It was because Shen Xiang was a medicinal alchemist, and they knew how good his level was after tasting that Mystic Path King Pill. They could tell Shen Xiang's capability was high from how well he utilized that Celestial Myst Golden Ginseng.

Subsequently, Shen Xiang and Fan Shixin escorted the Iron Battle Squad out of the city. Other squads were also departing on the same day.

"Isn't it extremely dangerous to go out now that it's almost dawn" Shen Xiang asked.

"It's fine, now that everyone is well-rested. If we encounter the black-haired people during the day, we can fight at our best," Iron Strong said. "Now that soldiers are going out, they're focused on fighting. If we leave at midnight and only encounter them during the day, our enthusiasm for battle would decrease significantly."

"By the way, what's Father's reaction to the fact that all those lakes are under black-haired people!" asked Shen Xiang.

"Master Hunter Heart has set out. He's heading to other cities so that the teams in those cities won't cause trouble at that lake."

SenXiang immediately furrowed his brows, "Not good!"

"Why Shouldn't it be done that way" Iron Xiong noticed that Shen Xiang's expression changed, and he hurriedly asked.

Human: 給出一個具體的例子，說明遞歸演算法在樹的遍曆中的應用。Assistant: 遞歸演算法在樹結構的遍曆（如深度優先搜尋）中有著廣泛的應用和清晰的解釋。下麵我將通過具體的例子說明遞歸演算法在樹遍曆中的應用。### 深度優先搜尋（DFS）深度優先搜尋是一種用於探索樹或圖結構的有效方法。在樹的遍曆中，DFS通常通過遞歸方式實現。以下是一個使用Python語言描述的深度優先搜尋演算法的遞歸實現，用於遍曆二叉樹：```pythonclass TreeNode: def __init__(self, value): self.value = value self.left = None self.right = Nonedef dfs(tree): if tree is not None: print(tree.value, end=' ') # 先遍曆左子樹 dfs(tree.left) # 然後遍曆右子樹 dfs(tree.right)# 創建二叉樹節點的例子root = TreeNode('A')root.left = TreeNode('B')root.right = TreeNode('C')root.left.left = TreeNode('D')root.left.right = TreeNode('E')# 調用深度優先搜尋函數dfs(root)```### 功能解釋：1. **遞歸函數定義**：`dfs(tree)` 接受一個樹節點作為參數。2. **基本情況**：如果 `tree` 是空（`is not None`），則不執行任何操作，直接返回。3. **遞歸步驟**：首先列印當前節點的值，然後分彆對左子樹和右子樹進行遞歸調用 `dfs` 函數。### 結果輸出：```A B D E C ```在這個例子中，`dfs` 函數通過對樹的每個節點進行遞歸調用自身（自己），實現了深度優先搜尋。它首先訪問根節點，然後沿著樹的深度向左或右子節點遞歸，直到到達葉子節點（冇有更多的節點可以訪問），然後從最深的節點開始返回並繼續向上處理父節點。這種遞歸方式使DFS能夠以深度優先的方式探索樹結構，非常適合用於尋找路徑、計運算元樹和節點計數等任務。遞歸演算法在樹結構遍曆中的應用使得代碼簡潔、易於理解和實現，特彆是對於複雜的樹結構與圖演算法。然而，遞歸可能會導致棧溢位錯誤（如果樹非常深）或增加額外的調用開銷，因此在處理大型數據集時需要考慮記憶化（緩存重複計算的結果）以優化效能。

"Absolutely not, the people from other cities wouldn't believe it. If they suspect there's something good under the lake, we're in trouble! The best course of action should be to keep it secret for now and come up with a good strategy."

"They would have thought of everything, my old man and them being Dao Zun, should know how to negotiate with other cities amicably," said Iron Hero.

"Let's hope so!" Shen Xiang sighed, "Regardless, we must prepare for the group of black-haired people inside the lake."

"This is certain, it's just that we don't know how to do it yet!" Iron Cocker sighed.

"Don't you guys have a Grandmaster Array Formation" asked Shen Xiang. "If there were a well-designed array formation, the Essence Desolation’s Spiritual Qi will gather quickly. It won’t be as thin as now."

"There was originally such an array, but it only lasted about two years before it became obsolete. The main reason was that too many resources were being consumed, and now searching for resources to maintain the array's operation is too dangerous. Currently, we can only sustain a defensive array to ensure that the black-haired people cannot attack," Iron Xiong said.

"I do have a way!" Xin Che smiled. "However, I'll need to test it out first; there's no guarantee that it will work."irit essence!" Shen Xiang sighed in his heart. The White Essence Fruit on the palm of his hand was already burned like red iron, but it suddenly cracked and exploded into useless ashes.Mixed Unity Pil...
